Abstract
Description
Die Erfindung betrifft ein elektromagnetisches Relais mit folgenden Merkmalen:
- Ein Gehäuse besitzt eine Kappe mit einer im wesentlichen geschlossenen Oberseite, geschlossenen Seitenwänden und einer offenen, durch ein Bodenteil verschließbaren Bodenseite,
- in dem Gehäuse sind ein Kontaktsystem mit herausgeführten Kontaktanschlußelementen sowie ein Magnetsystem angeordnet, dessen Spule benachbart zur geschlossenen Oberseite der Kappe liegt, und
- die Wicklungsenden der Spule sind jeweils mit in einem Spulenkörper verankerten Stützelementen verbunden, welche ihrerseits elektrisch leitend mit durch die Bodenseite herausgeführten Spulenanschlußelementen verbunden sind.
- A housing has a cap with an essentially closed upper side, closed side walls and an open bottom side which can be closed by a base part,
- in the housing a contact system with lead-out contact connection elements and a magnet system are arranged, the coil of which is adjacent to the closed top of the cap, and
- the winding ends of the coil are each connected to support elements anchored in a coil body, which in turn are connected in an electrically conductive manner to coil connection elements led out through the bottom side.
Ein Relais mit dem genannten Aufbau ist beispielsweise aus der DE-A-38 35 105 bekannt. Durch die dort vorgesehene Anordnung der Spule oberhalb des Kontaktsystems im geschlossenen oberen Bereich des Gehäuses wird ein schmaler Aufbau erreicht. Durch die Anordnung der Kontaktelemente in der Nähe der Anschlußseite im unteren Teil des Gehäuses werden auch kurze elektrische Verbindungen zwischen den Kontakten und den Zugehörigen Anschlußstiften gewährleistet, was nicht nur eine Ersparnis an Material und Bearbeitungsschritten ermöglicht, sondern auch Vorteile hinsichtlich der Wärmeableitung und der Isolierung zwischen den Kontaktelementen und dem Magnetsystem bringt. Deshalb wird diese Bauform bevorzugt für Starkstrom- und Netzrelais eingesetzt.A relay with the structure mentioned is known for example from DE-A-38 35 105. The arrangement of the coil provided there above the contact system in the closed upper region of the housing achieves a narrow construction. The arrangement of the contact elements near the connection side in the lower part of the housing also ensures short electrical connections between the contacts and the associated connection pins, which not only enables savings in material and processing steps, but also advantages in terms of heat dissipation and insulation between the contact elements and the magnet system. For this reason, this design is preferred for heavy current and mains relays.
Durch die Anordnung der Spule im oberen Bereich des Gehäuses ist es allerdings erforderlich, die Spulenanschlußelemente über eine verhältnismäßig lange Strecke bis zur Anschlußseite des Relais zu führen, wobei aber die Isolierung zu den Eisenkreisteilen des Magnetsystems und zu den Kontaktelementen gewährleistet werden muß. Insbesondere beim Einsatz des Relais an höheren Spannungen erfordert diese Isolierung, entweder in Form entsprechender Ansätze des Spulenkörpers oder in Form zusätzlicher Isolierteile, einen nicht unbeachtlichen Raum im Gehäuse.The arrangement of the coil in the upper region of the housing, however, makes it necessary to connect the coil connecting elements over a relatively long distance to the connection side of the Relay to lead, but the insulation to the iron circuit parts of the magnet system and to the contact elements must be ensured. Especially when using the relay at higher voltages, this insulation, either in the form of appropriate approaches of the coil body or in the form of additional insulating parts, requires a not inconsiderable space in the housing.
Aufgabe der Erfindung ist es, ein Relais der eingangs genannten Art sowie ein Herstellverfahren für dieses Relais anzugeben, bei dem unter Beibehaltung des grundsätzlichen Aufbaus eine einfache und platzsparende Verbindung von den Wicklungsenden der Spule zur Anschlußseite des Relais ermöglicht wird. Insbesondere soll dabei die Isolation zwischen Spulenanschlußelementen und Magnetkreis sowie Kontaktelementen ohne zusätzlichen Raumbedarf sichergestellt werden.The object of the invention is to provide a relay of the type mentioned and a manufacturing method for this relay, in which a simple and space-saving connection from the winding ends of the coil to the connection side of the relay is made possible while maintaining the basic structure. In particular, the insulation between the coil connection elements and the magnetic circuit and contact elements should be ensured without requiring additional space.
Zur Lösung dieser Aufgabe besitzt ein erfindungsgemäßes Relais die folgenden zusätzlichen Merkmale:
- Die Spulenanschlußelemente sind jeweils in einer Seitenwand der Kappe isoliert von der Bodenseite bis in den Bereich der Oberseite der Kappe geführt und münden in einer nach außen offenen Vertiefung der Kappenoberseite,
- die Stützelemente des Spulenkörpers sind in Stecköffnungen zur Kappenoberseite geführt und münden ebenfalls jeweils in einer der Vertiefungen und
- in jeder Vertiefung ist das jeweilige Ende eines Stützelementes mit dem Ende eines Spulenanschlußelementes leitend verbunden.
- The coil connection elements are each insulated in a side wall of the cap from the bottom to the area of the top of the cap and open into a recess on the top of the cap open to the outside.
- the support elements of the coil body are guided in plug-in openings to the top of the cap and likewise each open into one of the depressions and
- in each recess the respective end of a support element is conductively connected to the end of a coil connection element.
Bei dem erfindungsgemäßen Relais sind also die Spulenanschlußelemente isoliert unmittelbar in der Wand der Kappe geführt, vorzugsweise eingebettet. Dadurch ist innerhalb des Gehäuseraumes weder Platz für diese Spulenanschlußelemente selbst noch für zusätzliche Isolierwände erforderlich. Der Raumbedarf ist somit allein durch die Ausdehnung des Magnetsystems und des Kontaktsystems bestimmt. Die leitende Verbindung zwischen den Enden des jeweiligen Stützelementes und des zugehörigen Spulenanschlußelementes kann grundsätzlich auf verschiedene Weise mit üblichen Verfahren hergestellt werden. In Betracht kommen dabei Schweißverbindungen oder Lötverbindungen, wenn die Konstruktion so gestaltet werden kann, daß die zu verbindenden Enden für Schweißelektroden oder für Lötvorrichtungen zugänglich sind und gegebenenfalls auch die Beständigkeit gegen die Löttemperatur in der Umgebung der Lötstelle gewährleistet ist. Besonders vorteilhaft ist jedoch eine Verbindung mittels eines Leitklebstoffes, der in die jeweilige Vertiefung eingebracht wird und bei relativ niedriger Temperatur aushärtet. Um die Isolation der Verbindungsstelle nach außen zu gewährleisten, wird vorzugsweise auf die Verbindungsstelle bzw. auf den Leitklebstoff eine Isolierstoffschicht aufgebracht, die die Vertiefung nach außen abschließt.In the relay according to the invention, the coil connecting elements are thus directly isolated, preferably embedded, in the wall of the cap. As a result, neither space for these coil connection elements themselves nor for additional insulating walls is required within the housing space. The space requirement is thus determined solely by the expansion of the magnet system and the contact system. The conductive connection between the ends of the respective support element and the associated coil connection element can in principle be produced in various ways using conventional methods. Welded connections or soldered connections come into consideration if the construction can be designed in such a way that the ends to be connected are accessible for welding electrodes or for soldering devices and, if necessary, the resistance to the soldering temperature in the vicinity of the soldered joint is also guaranteed. However, a connection by means of a conductive adhesive, which is introduced into the respective depression and cures at a relatively low temperature, is particularly advantageous. In order to ensure the insulation of the connection point from the outside, an insulating material layer is preferably applied to the connection point or to the conductive adhesive, which closes off the recess from the outside.
Ein bevorzugtes Verfahren zur Herstellung des Relais besteht im wesentlichen aus folgenden Schritten:
- Die Kappe wird mit den in mindestens einer Seitenwand eingebetteten Spulenanschlußelementen, mit Vertiefungen an der Kappenoberseite im Bereich der Enden der Spulenanschlußelemente und mit Stecköffnungen im Bereich der Vertiefungen ausgeformt,
- in die offene Kappe werden das Magnetsystem und das Kontaktsystem eingesetzt, wobei im Spulenkörper eingebettete Stützelemente mit freien Enden in die Stecköffnungen der Kappe eingesteckt werden, und
- in den Vertiefungen an der Kappenoberseite wird je ein Stützelement mit einem Spulenanschlußelement leitend verbunden.
- The cap is formed with the coil connection elements embedded in at least one side wall, with depressions on the top of the cap in the area of the ends of the coil connection elements and with plug openings in the area of the depressions,
- the magnet system and the contact system are inserted into the open cap, with support elements embedded in the coil body having free ends being inserted into the plug-in openings of the cap, and
- in the recesses on the top of the cap, a supporting element is conductively connected to a coil connecting element.
Soll das Gehäuse waschdicht abgeschlossen werden, so ist es von Vorteil, vor der Herstellung der leitenden Verbindung in den Vertiefungen die Bodenseite der Kappe mit Vergußmasse abzudichten, wobei bis zur Aushärtung der Vergußmasse die Stecköffnungen der Kappe als Lüftungslöcher dienen können. Durch Einbringen von Leitklebstoff in die Vertiefungen können dann jeweils die Stützelemente und Spulenanschlußelemente leitend verbunden, zugleich aber auch die Stecköffnungen dicht verschlossen werden. Durch Aufbringen von Isolierstoff auf die leitende Verbindung in den Vertiefungen können diese Vertiefungen zusätzlich abgedichtet und die leitenden Verbindungen nach außen isoliert werden.If the housing is to be sealed in a wash-tight manner, it is advantageous to seal the bottom side of the cap with potting compound in the depressions before the conductive connection is made, the plug openings of the cap being able to serve as ventilation holes until the potting compound has hardened. By introducing conductive adhesive into the wells, each can then the support elements and coil connection elements are conductively connected, but at the same time the plug openings are sealed. By applying insulating material to the conductive connection in the depressions, these depressions can be additionally sealed and the conductive connections can be insulated from the outside.

In die Vertiefungen 18 ist von außen her Leitklebstoff 21 eingefüllt, welcher die Stützelemente 15 und die Spulenanschlußelemente 20 jeweils elektrisch leitend verbindet. Über den Leitklebstoff 21 ist eine Isolierstoffschicht 22 aufgebracht, welche das Gehäuse nach oben abschließt und isoliert.
Bei der Montage des Relais wird zunächst das Magnetsystem in die Kappe 1 eingesetzt und befestigt, wobei die Stützelemente 15 durch die Stecköffnungen 17 gesteckt werden. Durch Einsetzen des Kontaktsystems mit dem Träger 5 wird das Gehäuse zur Unterseite abgeschlossen. Durch Aufbringen einer Schicht Vergußmasse 23 wird das Gehäuse abgedichtet, wobei die Stecköffnungen 17 als Lüftungslöcher wirken, die beim Aushärten der Vergußmasse 23 einen Druckausgleich ermöglichen. Danach wird der erwähnte Leitklebstoff 21 in die Vertiefungen 18 eingebracht, und diese werden dann nach außen durch Einbringen der Isolierstoffschicht 22 abgeschlossen.When assembling the relay, the magnet system is first inserted and fastened in the cap 1, the
